In 36 patients with angina pectoris during complex invasive diagnostic procedure the changes of global and regional systolic heart function by intravenous application of 200 mg pentoxifylline were examined. We observed a significant decrease of preload (reduction of LVEDP and MCS, LVEDV was not influenced) and an improvement of myocardial pump function, possibly combined with a favourable influence on alterated myocardial blood supply. In case of perfusion disturbances of the LV anterior wall the pentoxifylline injection was followed by signs of coronary-steal-mechanism in the LV posterior wall region. We did not found significant changes of afterload. Thus the acute hemodynamic effects of an intravenous application of pentoxifylline are comparable with those of nitrates and non-glycoside-cardiotonic substances with a predominant myocardial effect.

The study of quality of life (QoL) in a French cohort of patients suffering from angina pectoris was one of the objectives of the ELAN longitudinal study. It concerned 3,954 subjects (76% males) mean age: 67 +/- 11 years, followed up by 613 cardiologists which were invited to complete a series of baseline sociodemographic and clinical data and to answer a series of questions upon one year outcome (3,261 medical records available). QoL was assessed at baseline via a self-administered 12-item general questionnaire, the Short-Form 12 (SF-12), enabling to compute a mental component summary (CS-12) and a physical component summary (PCS-12) score. Mean MCS-12 in the ELAN cohort (49 +/- 7.5) was very close to the standards derived from general American population (50 +/- 10) or to the data available in a general French population (51.2 +/- 7.4). Whereas mean PCS-12 was hardly lower (about one standard deviation) in comparison with general American population (50 +/- 10) or with a general French population (48.4 +/- 9.4). QoL was higher in males and linked to age in a contrasted way (higher MCS-12 and lower PCS-12 in elderly; p < 0.0001). It depended on the clinical condition (lower MCS-12 associated with mixed-type angina pectoris or with more severe angina and with persistent smoking; lower PCS-12 associated with mixed type or more severe angina, with cardiac failure episodes, arteritis obliterans, stroke antecedents or left ventricular hypertrophy). Both scores were negatively correlated, in multivariate regression analysis, with the severity of persisting angina at one year, after controlling for the severity of baseline angina and the other confounding variables. Above all, MCS-12 and especially PCS-12, predicted major coronary events at one year (death, myocardial infarction, angioplasty, coronary by-pass surgery). In a multivariate logistic regression analysis, low baseline PCS-12 was associated with higher risk for cardiovascular death at one year (OR = 2.44; 95% CI = 1.25-4.74; p < 0.01). These results confirm the clinical validity of SF-12 (cross sectional stage of the study) and stress its prognostic value independent from the other risk factors (longitudinal stage of the study).

The aim of this study was to compare the therapeutic effects of muskone, a traditional preparation containing slender Dutchmanspipe root (MCS) used to treat angina pectoris and related conditions, muskone containing inula root (MCI) in place of MCS, and muskone (M) without either slender Dutchmanspipe root (S) or inula root (I) on acute myocardial infarct (AMI) in rats and the pain response in mice. The AMI model was established by ligating the left anterior descending coronary artery (LAD). The AMI rats were treated with MCS, MCI, M, S and I, respectively, before the surgical operation. Plasma endothelin (ET), 6-keto-prostaglandin F(1alpha) (6-keto-PGF(1alpha)), thromboxane (TXB(2)) and myocardial apoptosis were detected, the ratio of 6-keto-PGF(1alpha) level to TXB(2) level (6-keto-PGF(2alpha)/TXB(2)) was calculated, and the infarct size was determined. In the pain relieving study, the prophylactic treatments with MCS, MCI, M, S, I and aspirin were administered to the mice once a day for 5 days, the response latency and the number of abdominal contractions after the stimulus of intraperitoneal injection of acetic acid were recorded. The results show that MCS, MCI and M significantly ameliorated plasma ET, TXB(2), 6-keto-PGF(1alpha) and 6-keto-PGF(2alpha)/TXB(2) levels, reduced infarct size and opposed myocardial apoptosis. Simultaneously, they also significantly reduced the abdominal contractions and also prolonged the response latency induced by acetic acid in the mice. S and I only showed a degree of relieving pain, but their efficacy was weaker than that of MCS, MCI and M, and they had little cardioprotective effect. In conclusion, MCS, MCI and M had a significant cardioprotective and analgesic effect, and they had similar efficacy. S and I only had a secondary analgesic effect. Removing S from the MCS or replacing S with I did not influence the cardioprotective effect and analgesic effect.
